Question: When Hogan gives Klink $100 for the cuckoo clock, the bill handed over was a crisp American $100 note. How did Hogan get an American $100 note? At best, in this time period, he should only have Reich Marks. And how would he have 333 Marks, 33 pfennigs? Unless he had a side businesses going, this seems unlikely.

Chosen answer:Hogan and his men are running a spy ring out of the camp, they have access to supplies from outside. (In another episode, they have to convince a defecting German officer that they're legitimately working for the Allies by arranging a specific personal ad to run in the next day's London Times, so a new $100 bill is not beyond their capabilities).

During WW2 Robert Clary, who played Louis LeBeau, had been imprisoned at Drancy internment camp in France, and at Buchenwald Nazi concentration camp where he was tattooed with the number "A5714." He was the youngest of 16 children. Twelve members of his immediate family were sent to Auschwitz, and perished.
